Through application to soil in farmer's fields, biochar both can help increase soil fertility and store carbon emissions. Photo: Feral Arts via flickr. More new info on the potential of biochar to help combat climate change: A study in the journal Nature Communications shows that up to 12% of the world's greenhouse gas emissions caused by humans could be offset by p...Read the full story on TreeHugger

photo: Beth Rankin via flickr With Congress still not able to get out of its own way and actually move forward any legislation with the word 'climate' in it, what options does President Obama have to make good on his oft-stated commitments to make reductions in greenhouse gas emissions? Leaving aside the EPA mandating carbon emission reductions (remember it's now officially a pollutant), over at Read the full story on TreeHugger

photo: US Geological Survey via flickr Knock off one natural counterbalance to global warming: A new study in the Science shows that any hope that as Arctic sea ice melts and opens up new areas of open water potentially increasing its ability to store carbon emissions is ill-founded. In fact any increase in carbon storage will be short-lived and ...Read the full story on TreeHugger

Image via a Green Living You'd be forgiven for thinking that AB 32, California's climate change law, was truly controversial. Republican candidates running for office this year have taken to publicly bashing it, calling it a job killer and worse. And given that the effort to reign in carbon emissions on a national level just deflated because it was viewed by senators as too controversial as well, you might think that fighting climate change is a contentious issue across the board. Well, it's not. No matter how badly California's GOP hopefuls batter the law, the public st...Read the full story on TreeHugger

The carbon intensity of coal is so high that CCS technology will only slightly reduce emissions, the report authors say. Photo: Joost J Bakker via flickr. Another take on the how to transition from coal-based electricity and its huge carbon emissions to low-carbon power sources, this time from two researchers from Rice University: A new paper coming out of Rice's Baker Institute for Public Policy recommends using natural gas to replace the US' coal po...Read the full story on TreeHugger
